S85 CSL Competition Carbon Intake System

Swipe right for info.

Test fitment: done.

You're seeing the 3D printed prototypes. Production of carbon units is on.

Massively enlarged sealed intake inlets

Current owners of sealed intakes will be able to solely upgrade the inlets. The lower housing, filter element and clamp stays the same.

[...] with matching side inlets.

The core of OE+ variant plenum stays the same, but new side inlets are fitted.
Build journal: a special series
Reimagining the original BMW CSL prototype.

The CSL Plenum OE+ variant introduced in 2022 was a first steps towards bringing to market the first commercially available V10 CSL carbon intake system.

A few of us wanted more. We wanted the original.

The Competition Spec aims at achieving this objective with a massively enlarged, fully sealed, complete carbon intake system running exclusively on AlphaN.

In this Special Series, I build upon the original series and dive into the development, test fitment and upcoming impressions of the Competiiton variant.

Enjoy,

Stage Tuning

Tuning is often offered in "stages" that optimize for your peripheral performance upgrades.

Here's how Sal defines his stages. 

Stage 1:

Standard cars. I highly recommend the sealed air intakes

Stage 2:

Optimized for primary cat deletes & aftermarket long tube headers.

Stage 3:

Optimized for V3 long-tube, equal length headers.

Extra specifications available: 

  • Raised RPM limit to 8500rpm
  • Idle RPM adjustments
  • VMax Limit removal
  • Cold start delete
  • Power calibrations with changes made to ignition, fuel, torque and VANOS maps

Mandatory AlphaN mapping

The massive increase in air volume requires Alpha N performance tuning.

The larger inlets will not have MAF bungs to optimize for space.

A new pair Intake Air Temperature sensors will be required and included along with the wiring and connectors.

It's counterintuitive, but it works.

I documented in vast details the installation process of the OE+ plenum. I will further document the Competiton Spec specifics.

If your mechanic thinks he's smart and skips this, don't pay the bill.

FAQ

Yes.

No! However, Sal and I are looking to see if a tune can be optimized for the larger air volume. TBD.

I first want to test these before making them available.

Hear the OE+ variant

I expect the Competition Spec to be even louder.

The sound is very S54 CSL-esque: addicting, intoxicating - all apply.

@AR24

Overall the car feels more responsive, pulls like a train!!

Sal @ InfinityDesign
Legacy knowledge.

InfinityDesign's unique product design and engineering is crafted by the grand-daddy of the most popular S85 products and tuners to hundreds of S85s: Salman.

As a former Evolve co-owner, he headed engineering & development for all products.

He notably signed off on numerous popular V10 products: e-tronic exhaust systems, headers, cat deletes, carbon intakes along with the V8 supercharger kits & tuning maps during the 2000s until he exited the company in 2015.
